Ingredients You’ll Need

For the Cajun Pasta

• 12 oz penne pasta — provides the hearty base that holds onto the creamy sauce.
• 14 oz andouille sausage, sliced — adds smoky, spicy flavor and a satisfying protein element.
• 2 tablespoons olive oil — helps brown the sausage and sauté the vegetables.
• 1 medium bell pepper, diced (red or yellow) — adds sweetness, color, and texture.
• 1 medium onion, diced — creates a savory aromatic foundation for the sauce.
• 4 cloves garlic, minced — enhances the Cajun flavor with a fragrant savory note.
• 2 teaspoons Cajun seasoning — provides the signature spicy and smoky seasoning blend.
• 2 tablespoons tomato paste — adds richness, acidity, and deeper color to the sauce.
• 1 cup low-sodium chicken broth — helps build the sauce while adding savory flavor.
• 1 cup full-fat heavy cream — creates the creamy, luxurious sauce texture.
• ¾ cup freshly grated Parmesan cheese — adds salty, nutty richness and helps thicken the sauce.
• Salt and pepper, to taste — balances and enhances the overall flavors.

Step-by-Step Instructions

1. Cook the Penne Pasta

Bring a large pot of salted water to a boil and cook the penne according to package directions, reducing the cooking time by about 2 minutes. Drain the pasta while still slightly firm, reserving ¾ cup of pasta water to help adjust the sauce later.

2. Brown the Andouille Sausage

Heat olive oil in a large skillet over medium-high heat. Add sliced andouille sausage and cook for 3–4 minutes until browned and fragrant, then remove it from the skillet and set aside.

3. Sauté the Aromatics

Using the same skillet, add diced onion and bell pepper. Cook for 3–4 minutes until softened and the onion becomes translucent, then add minced garlic and cook for another minute until fragrant.

4. Develop the Cajun Flavor Base

Add Cajun seasoning and tomato paste to the vegetables, stirring well to coat everything. Cook for about 1 minute to toast the spices and deepen the flavor of the sauce.

5. Create the Sauce Foundation

Pour in the chicken broth and scrape the bottom of the skillet to release any flavorful browned bits. Simmer for about 2 minutes to slightly reduce the liquid and concentrate the flavors.

6. Add the Creamy Element

Reduce the heat to medium-low and stir in the heavy cream. Simmer for 3–4 minutes until the sauce begins to thicken and becomes smooth.

7. Combine Pasta and Sausage

Return the browned andouille sausage to the skillet along with the cooked penne. Toss gently until every piece of pasta is evenly coated with the Cajun cream sauce.

8. Finish with Parmesan

Remove the skillet from heat and stir in freshly grated Parmesan cheese until melted and smooth. Adjust seasoning and add reserved pasta water as needed until the sauce reaches the desired consistency.

Recipe Notes & Tips

• Reserve Pasta Water — The starch from pasta water helps emulsify the sauce and allows it to cling better to the penne.
• Use Fresh Parmesan — Freshly grated cheese melts more smoothly and prevents a grainy sauce texture.
• Do Not Overcook Pasta — Slightly undercooked pasta absorbs the sauce while maintaining the perfect bite.
• Brown the Sausage Properly — Allowing the andouille to caramelize enhances its smoky flavor.
• Control the Spice Level — Adjust Cajun seasoning depending on your preferred heat level.
• Add Cheese Off Heat — Stirring Parmesan after removing the pan from heat creates a smoother sauce.

Storage & Serving Tips

Troubleshooting Common Issues

• Sauce Is Too Thick — Add reserved pasta water gradually until the sauce loosens.
• Sauce Looks Grainy — Use freshly grated Parmesan and add it off the heat.
• Pasta Becomes Mushy — Cook the penne slightly less before combining with sauce.
• Dish Is Too Spicy — Reduce Cajun seasoning or balance with additional cream.

Why This Recipe Works

This recipe works because it builds flavor through multiple cooking techniques rather than relying on a single seasoning step. Browning the andouille sausage creates a smoky foundation, while sautéing onions, peppers, and garlic develops aromatic sweetness and depth. Toasting the Cajun seasoning with tomato paste intensifies the spices before the cream and broth transform them into a smooth, flavorful sauce. The reserved pasta water adds starch that helps bind the sauce to the penne, creating a silky texture that coats every bite. At approximately 460 calories per serving, this creamy pasta provides a satisfying balance of carbohydrates, protein, and richness while remaining adaptable for lighter ingredient swaps.

With its quick preparation, customizable ingredients, and restaurant-quality flavor, it is an excellent choice for both busy nights and special occasions.
